I agree with BSB67, would not want to grind for clearance on an engine of mine. I had the same issue when I built my 499 stroker on a B block. Solution was to heat one side of the pickup tube and squeeze it just enough to provide the necessary clearance. See photos for results.
Looks like a nice work👍, but do not the heat up of the pipe like that harden the material even more and make it more prone to cracking, the material in the pipe is from beginning pretty ductile.
